Equalization of Loudspeaker Resonances Using Second-Order Filters Based on Spatially Distributed Impulse Response Measurements

A new approach for identifying and equalizing resonances in loudspeakers is presented. The method optimizes the placement of poles and zeros in a second-order filter by minimization of the frequency-dependent decay. Each resonance may be equalized by the obtained second-order filter. Furthermore, the use of spectral decay gives opportunity for optimizing on multiple measurements simultaneously making it possible to take multiple spatial directions into account. The proposed procedure is compared to direct inversion and minimum-phase equalization. It makes it possible to equalize precisely the artifacts responsible for ringing, while being largely unaffected by other phenomena such as diffractions, reflections, and noise.
